tsarnaev. an exclusiveagainsttamerlan. asource in russia tells nbc news russian intelligence reached out to the fbi last november about the 26-year-old. and crime scene units are back at the bomb site in boston right now. they're placing debris into garbage trucks. crews were seen sifting last night throughout that debris. let's go to pete williams. with a good afternoon to you, pete, let's talk first about the status of the charges in this case and what the likely charges will be. >> yes, i think the odds are pretty good that we'll see these charges in the next couple of hours. they're putting the final touches on them now. and we expect to learn a little more about what the fbi has assembled based on its investigation of the bombing. so perhaps there will be some new details that we'll get. in terms of the charges, i would think at the very least they'll charge him with the bombing, with a terrorism offense for that. and interestingly enough, under the federal statutes, which apply here, use of a weapon of mass destruction, which is the federal law version of what a bomb is, if death r

: eric shawn live in boston. eric, thank you. we are still trying to get to the real storyontamerlantsarnaev'strip to russia last year and his possible ties to terrorism and islamic extremism. chief intelligence correspondent catherine herridge is following that thread tonight. >> the fbi's handling of tamerlan tsarnaev in 2011 and six-month trip to russia the following year now face congressional scrutiny. >> was your department aware of his travels to russia and, if you weren't, the reason? >> yes. the system pinged when he was leaving the united states. by the time he returned all investigations had been -- the matter had been closed. >> napolitano said the lookout system that flags agents federal investigation no longer active when tamerlan returned from russia in july of 2012. >> the system picked up departure but did not pick him coming back, correct? >> the fbi text alert on him at that point was more than a year old and had expired. >> napolitano's pluck contradict briefing given by the fbi director. >> after talking to the fbi they told me they had no knowledge of him leav

question this morning is: how much did other members of their family know? keep in mindthattamerlan, the26-year-old suspect who was killed on thursday night moving into friday, that he was married. he was married to an american woman who became a muslim after she married him. they had a three-year-old daughter together. it's questionable now whether or not they were actually still together at the time of this bombing. some sources are saying that she, catherine, pictured here, had moved back home with her mother, judith, with the baby. and maybe that would be when tamerlan ended up going back to russia for those six months because if you're married and you have a small child, you might wonder, that would be suspicious to be gone for six months. >>steve: she is on the cover of the new york post today because she always dreamed of growing up, joining the peace corps and serving this country and others abroad. then she got tangled up with this guy, converted to islam. next thing you know, she dropped out. there is an interesting item in the "wall street journal" today that says essent

muslims more than it does. that's going to take it up discussion. we learnedtodaytamerlanwaskicked off a mosque because being too radical. what peter king will do with that information, based on experience, say that's proof we need to more closely monitor people in this country. i'm not sure you need to go that far. this is somebody who was in a citizenship cue and had that process delayed because of going back and forth to russia. it might have been a specific case we missed and not something to look at as it expands ever more the investigation of muslims in general. something the system should have captured but we will discuss broad solutions, broad ideas not just republicans but national security hawks wanted whatever the situation is. >> we'll leave it there. go ahead, lynn. jump in. >> a quick point. this comes as the immigration bill is being kbeebt edebated i senate. >> we'll talk about that later in the broadcast. thanks to you all. appreciate your time. >>> the fbi again, interviews, in e did not find any terrorist links to him. how did that happen? i'll ask a senior member of
